I love my red aoto. It is my favorite stone and I have lots, both naturals and synthetics. it cuts fast, has a nice feel, great mud and that wonderful earthy smell. nice sharp edge, which I usually use as my working edge. In fact when I dropped and shattered my first one, I got a replacement -and Maxim was awesome- he gave me a pity discount and sent me an even bigger stone.

I just used my red aoto on a new Dovo straight razor that I repaired for a friend of a friend. Made the jump from Bester 1200x to other naturals very easily. I was hearing Maksim in my head saying don't use this on a razor you idiot but hey it worked.

I know it can take a while to figure them out and since I trusted the stone to be good it could only be me, that's why it's taken so long to really figure out what's up with it.
What's wrong with "here", it's the thread to go to when it comes to Red Aotos.
Don't take it wrong, I'm not trying to put the stone down as a bad rock, as mine seems to be a different beast how could I even tell.
Now I had some friend try it to, none can get it to sharpen as in your videos, all we get is red/brown slurry and lots of it if you use some pressure, not at all as when you do it, you get visible steel.

Can you maybe post a picture of it ?? Or make small video. Now i am quite curries my self. I must admit i cant remember witch one i sold you as it have been so long.
But if it is as you describe it most be one of a 100 Red Aotos truly unique stone

It was one of the early ones I believe, it got darker stripes in it
My camera sucks but will try and see what I can do.

I did try it out again yesterday, an old Swedish carbon blade, not very hard steel.
The slurry on the Red Aoto goes from reddish to more brown.
On the other "coarse" stones, regular Aoto, White Binsu, Amakusa and Hideriyama it goes from any color to black.
Any suggestions on how more to test it?
